WINDOW-LOCKING DEVICE.

Specification of Letters Patent.

Patented Apr. 27, 1915.

Application led April 29, 1913. Serial No. 764,329.

To all whom it may concern Be it known that I, JOHN G. Locks, a citizen. of the United States, residing at Passaic, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Window-Locking Devices; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.'

The present invention has reference, generally, to improvements in locking device for sash-windows and the like; and the invention relates, more particularly, to simple, cheap, efficient and easily manipulated locking device for sash-windows which serves to securely lock the window-sashes when in closed position, and also to securely lock the window-sashes in partially open position against a further opening of the same, when it is desired to have the window-sashes partly open for the purpose of securing interior ventilation.

The present invention has for its principal object to provide a simple and easily operated window locking device, which will in operation automatically lock the windowsashes when the same are moved into their closed position in the window frame and which will also permit the window-sashes to be partially opened to obtain ventilation, but which will still maintain the same locked against further opening when in such partially opened or Ventilating-position, said locking device being proof against manipulation or tampering with from the exterior of the window, when in either locking position, unless the window itself is destroyed.

A further object of the present invention is to provide in connection with a window locking device of the character above described, a means for releasing the bolt element of the locking device from its operative position so that the window-sashes may be completely opened.

Other objects of the present invention not at this time more particularly enumerated, will be clearly understood from the following detailed description of the present invention.

With the various objects of this invention in view, the same consists, primarily, in the novel window locking-device hereinafter set forth; and, furthermore, this invention consists in the novel arrangements and combinations of the various devices and parts, as well as in the details of the construction thereof, all of which will be hereinafter more fully described in the following specification, and then finally embodied in the clauses of the claim which are appended to and which form an essential part of this specification.

The invention is clearly illustrated in the accompanying drawings, in which Figure l is a face view of a window with the sashes thereof in closed position, and the novel 'locking device, made according to and embodying the principles of the present invention, being shown in operative connection with said window sashes and in normally locking relation thereto; Fig. 2 is a similar view illustrating said locking device in locking position when retaining said window-sashes in partially open position for the purpose of securing interior ventilation. Fig. 3 is an enlarged detail perspective view of the novel locking device in operative connection with the sashes of a window, the latter being shown in closed position and the locking-device in its automatically locking position. Fig. 4: is an enlarged detail longitudinal section taken on line 4:--4 in said Fig. l looking in the direction of the arrow Eig. 5 is a similar longitudinal section taken on line 5 5 in said Fig. 2, also looking in the direction of the arrow a2,- and Fig. 6 is a similar longitudinal section illustrating the operation of the means for releasing the bolt element from operative relation with the bolt receiving element of the locking device, so that said window sashes may be completely or entirely opened.

Similar characters of reference are employed in all of the hereinabove described views, to indicate corresponding parts.

Referring now to the said drawings, the reference character l indicates a windowframe in which are slidably mounted, in the usual manner, an upper window sash 2 and a lower window sash 3. Secured, in suitable position, to the meeting-rail 4l of said lower window-sash 3, by means of its screw-threaded shank 5 which screws into said meeting rail, is an eye-member 6, to which is pivotally connected or anchored, by means of its link-end 7 a bolt-element 8.

The free end of said bolt element 8 is provided with a transversely extending' headportion 9, preferably of'T-shaped, although if desired the same may be made L-shaped, or in any other suitable form.

The reference character 10 indicates a supporting -or bracket portion of a bolt receivinglelement, the same being designed to be connected with and supported upon one of vthe vertical stiles ;11 of said upper window-sash2 by said supporting or bracketportion'lO, and-to this end-said supporting or :bracket-portion `may be yprovided with two or more perforated tongues or lugs 12, through the perforations of which-the fastening screws l13 may be passed and screwed into said vertical stile 11. -Integrally connected with the inneredge of said supporting or Vbracket-portion 10 is an off-set portionV 111,the same-eXtendinginwar-dly along the inner edge of said vstile 11, and conneeted withsaid off-set portion 1st is the guard or `vkeeper-plate 15 of the said boltreceiving element,the same being positioned to project outwardly from the inner side of said stile 11, and disposed to extend longitudinally of said stile `11. Connected with said guard or keeper-plate 15 isa back or body-plate 16, the same being spaced rearwardly from saidguard or keeper-plate 15 and paralleling the same so as to provide an intervening space or runway 17. Saidguard or keeper-plate 15 and said back or bodyplatev16 are connected together at their upper ends by an end-member 18, which may be formed integrally with said respective plates, or which may be inserted between the same'and thus secured, said end-member respective plates.

providing a stop at the upper end of said space orfrunway 17 provided between said Formed adjacent to the lower end of said back or body-plate .16 is a rearwardlypbent or pressed portion 19 adapted =to provide in said back or bodyplate asuitably located depression or seat 20. The Aextreme lower end 21 of said back orV `body-plate 16, below said depression or seat 20, is bentforward so as to lie in contact with the lowervend of said guard or keeper-plate 15, to which vit is secured by rivets, or .any other suitable fasteningV means. In order to secure even greater lstrength at the jointure of the lower ends of said back or body-plate and said guard .or keeper-plate, the end of said back or body-plate may be bent around the end of said keeper-plate as at 22. Integral-ly formed with said backor body-plate 16 so as to extend'from thelongitudinal free edge of thev same is a side-portion 23 .which is bent to extend over or across the intervening space orrunway 17, at one side thereof, the

marginaledge 24 of said side-portion 23 being turned `over to engage ythe marginal odge of saidfguard or keeper-plate l5 as shown, or if desired said side-plate may be i made to extend from said keeper-plate, or lfrom both lkeeper-plate and back or bodyplate in various ways, so as to serve the purpose of closing the side of said space or runway 17, andV strengthening the assembled relation of said back or body-plate and in `.said -guard or keeper-.plate *.15 adjacent Y to-lowenend ofsaid -slotor-opening 25 is a hatch portion formed by thecutaway portion-26 -at the left marginaliedge .of said slot or opening, l,and the cutawayportion 27 at the right marginal edge of said kslot or opening. :Said hatchlserves as a means of entrance and exit orsaid head-'portion 9 of said bolt-element 8 into.'l said space vor runway l17 and'in engagement with said back or body-plate 16. A spring-member or plate 28 is secured by riveting Vor otherwise at its lower end to theplowerrendsofsaid back or body-plate and guard or keeperplate, the same extending upwardly sothat itsbody lies across said cutawayportion 27 thus normally closing said hatch against the removal therethrough of said Ahead-portion 9 of said bolt-element when the' latter is inserted or arranged operatively within said space'or runway 17. A push-.button -29 is connected ywith said spring-memberor plate 28 whereby the same may be depressed, in the manner shown in Fig. 6of the `drawings, thereby permitting said head-portion :L9 to rideup over said spring-member or plate and then be thrown; lout or removed through said hatch. .To this end the free -end of said spring-.member or plate 28 is so located as to Contact with .saidiback Aor body-plate when depressed at a point above'thealocation ofsaid depression or seat `20. `Suitably located upon and. connected withy said meeting-rail 4 or" said lower window-sashflisia bolt-holder v`8() which receives andholdsthe said bolt-element Swhen the same isl disengaged from its operative association lwith* said boltreceiving element, (as -showngby dotted 'lines in Figs. land 3) thus prevent-- ing the same rattling .or moving .about its sunk in Vsaidstile :so thatfsaid .guard-or keeper-plate 15 is flush with the stile surface, and when so arranged it will be obvious that the bracket-portion 10 and olf-set portion 14 may be dispensed with.

Having thus described the construction of my novel locking device I will now set forth the manner and advantages of its use when in operation.

vVhen the window sashes are closed the hatch in the keeper-plate 15 of said bolt receiving element is so located with reference to the free end of said bolt-element 8, that the latters head-portion 9 may be inserted therethrough and by pushing against the same said spring member or plate 28, is depressed so that said head-portion 9 will pass through said hatch. Now by either slightly raising the lower window-sash 3, or lowering the upper window-sash 2 the head-portion 9 is caused to ride along the surface of said spring-member or plate 28 and thus enter said space or runway 17, where the same contacts with said back or body-plate while the shank of said bolt-element rides in the slot or opening 25. portion 9 passes the end of said spring-member or plate 28, the latter springs back to normal initial position thus closing said hatch against the removal of said head-portion of the bolt-element from said space or runway 17 until said spring-member or plate 28 is again depressed to permit the same to ride up thereon and out through the hatch as above described. /Vhen the said bolt-element 8 with its head-portion 9 is thus arranged to ride in said space or runway 17 the window-sashes may be closed and then said head-portion 9, owing to the inclined disposition of said bolt-element 8, falls into said depression or seat 2O formed in said back or body-plate 16. When thus positioned said bolt-element serves to automatically lock the window-sashes against being opened, by reason of the stopped engagement of said head-portion 9 with said seat or depression 20, and any attempt to raise the lower window-sash 3 merely forces more firmly into the said seat or depression 20 the head-portion 9 of the bolt-element, or any attempt to lower the upper window-sash 2 merely forces the said seat or depression 20 more firmly against the head-portion 9 of said bolt-element. Now if it is desired to open either or both window-sashes partially for the purpose of admitting air for interior ventilation through the window, the said bolt-element 8 is oscillated to remove said head-portion 9 out of said depression or seat 20 and into said space or runway 17 This being done a limited movement of the sashes is permitted, the movement being stopped or limited by the engagement of said headportion 9 with the stop formed by the end member 18 which joins the upper end of said back or body-plate 16 and said guard When the said heador keeper-plate 15 thus closing the upper end of said space or runway 17. Of course any movement of the lower window-sash 3 pushes or slides the head-portion upwardly through the space or runway 17 until it is stopped by engagement with said end-member 18, and any movement of the upper window-sash 2 pushes or slides the bolt receiving element upon said head-portion until the end-member 18 engages said headportion, in both cases the shank of the boltelement 8 rides in said slot or opening 25 which is wide enough to permit its free movement, but which is not wide enough to permit the removal of the widened headportion 9 therethrough. It will thus be apparent that while such a limited opening of either or both window-sashes is obtainable, nevertheless the respective sashes are still maintained in such a locked condition as will prevent a full or complete opening of the same sufiiciently wide to permit entrance from the outside of the window. It will also be apparent that the locking device can not be tampered with from the exterior of the window when the same is thus partially opened for ventilation, since the head-portion 9 of the bolt-element can not be removed from the runway 17, and if the sashes are closed the said bolt-element immediately is engaged by the seat or depression 20, so that the sashes become at once automatically locked against even the limited opening permitted, unless the bolt-element is withdrawn from said depression or seat 20, by manipulation from inside of the window only, as above described.

It will thus be clearly evident that my present invention provides a very simple, strong, cheap and eflicient locking-device which permits a limited opening of the window-sashes for the purposes of ventilation.

I am aware that some changes may be made in the general arrangements and combinations of the several devices and parts, as well as in the details of the construction of the same, without departing from the scope of the present invention as set forth in the foregoing specification. Hence, I do not limit my present invention to the exact arrangements and combinations of the various devices and parts as described in the said specification, nor do I confine myself to the exact arrangements or detailsl of the construction of the said parts as illustrated in the accompanying drawings.
